The word is the red dot "load" of 13 grains in 30-06 is safe to use in M1s. I've tried it on my 03a3 and works fine. In fact I did a reduced load of 12 grains successfully.
I need to hear from people that have actually tried it, not from a friend of a cousin of a friend that used it and used it alot. If you haven't thats fine but be honest, no one wants to get someone hurt here.
Theres some concern that this might bend or snap the op-rod which can potentially kill you. As one can expect dying is not a desirable aspect of reloading. Also need to know will it cycle the action or not.
